BOOKING CHAIR.

nire rares I "WILLIAM M. BOENNING, OF PORT WASHINGTON, VISOONSIN.

ROCKING-CHAIR.

SPECIFICATION forming part of Letters Patent No. 585,422, dated June 29, 1.897.

Application filed November 27, 1896. Serial No. 613,502. (No model.)

To a/ZZ whom it may concern: l

Be it known that I, WILLIAM M. BOENNING, a citizen of the United States, and a resident of Port Vashington, in the county of Ozaukee and State of Wisconsin, have invented certain new and useful Improvements in Rocking- Ohairs; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention has for its object to provide a simple economical knockdown rockin g-chairg and it consists in certain peculiarities of construction and combination of parts hereinafter set forth with reference to the accompanying drawings and subsequently claimed.

Figure l of the drawings represents a partlysectional view of the major portion of a rocking-chair constructed according to my invention; and Fig. 2, a plan view illustrating the base and rocker mechanism of the chair, parts of this rocker mechanism being broken.

Referring by letter to the drawings, A A represent a pair of parallel bars set on edge and joined by intermediate rounds h to constitute the base of my improved rocking chair. Pivotally connected to each side bar of the base, near the extremities o f the same, are the lower ends of rods B O, that cross each other and have their upper ends likewise connected to the side bars D of a seat-frame, the latter being supported by said rods at the desired elevation clear of said base.

The parallel pair of rods B are shown connected bya round c, and rounds d e are shown connecting the other parallel pair of rods O, these latter rods being of greater length than those aforesaid for the purpose hereinafter specified. The rods O are shown as arranged to come inside of the ones B, and the round c, connecting the outer rods, is in the downward path of the others to serve as a stop for the same.

As herein shown, a spiral spring E may have hook-end connection under tension with the rounds c e, and resistance of the spring is therefore proportionate to the degree of tilt that may be imparted to the seat-frame in either direction. Consequently there is always a tendency of the movable parts toward their normal position herein shown.

The rods O are made longer than the ones B in order to obtain normal rearward tilt of the chair-seat,and the base extends far enough in rear of said seat t-o compensate for any tendency of the chair tovtopple backward.

The rods B O are preferably of wood and their pivots of metal, those shown being engaged with corresponding sockets in the side bars of the base and seat-frame. As herein fully illustrated, the pivots may be extremities of shouldered arms extending from metal sleeves F in driving iit on ends of rods B O, and these sleeves are provided with apertures for stay-nails g, driven into said rods.

The pivotal connection of the crossed rods with the base and seat-frame vinsures easy rocking action of the latter, the spring under tension operating to prevent sudden movement in either direction, thereby overcoming "the sensitiveness that otherwise exists.

In view of what has been shown and describedit is evident that the chair may be readily knocked down and the parts packed in comparatively small compass for storage and shipment.

Having now fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. A rockin g-chaircomprising a seat-frame, a base extended in rear of the seat-frame, and crossed rods in pairs pivotally connected to said seat-frame and base to support the former, the rods of the pair connecting the rear portion of the base with the aforesaid seatframe being longer than those of the other pair.

2. A rocking-chair comprising a seat-frame, a base extended in rear of the seat-frame, crossed rods in pairs pivotally connected to said seat-frame and base to support the former, the rods of the pair connecting the rear portion of the base with. the aforesaid seatframe being longer than those of the other pair, and a round uniting the short rods arranged in the downward path of the long rods.

3. A rockin g-chair comprising a seat-frame, a base extended in rear of the seat-frame, crossed rods in pairs pivotally connected to said seat-frame and base to support the former, the rods of the pair connecting the rear IOO portion of the base with the aforesaid seatington,in the eonntyof Ozaukee and State of frame being longer than those of the other isconsirnin the presence of two Witnesses.
